We present results from the first dedicated study in the time domain of the hard X-ray variability behavior of blazars on long timescales based on $\sim$13 years of continuous hard X-ray data in the 14-195 keV band.

An Optical Overview of Blazars with LAMOST. I. Hunting Changing-look Blazars and New Redshift Estimates [PDF]
The extragalactic γ-rays sky observed by the Fermi Large Area Telescope (LAT) is dominated by blazars. In the fourth release of the Fermi LAT Point Source Catalog (4FGL) are sources showing a multifrequency behavior similar to that of blazars but lacking

Searches for IceCube neutrinos from blazar flares using correlations with gamma-ray lightcurves [PDF]
Blazars have long been considered as accelerator candidates for cosmic rays. In such a scenario, hadronic interactions in the jet would produce neutrinos and gamma rays.

Probing Neutrino Production in Blazars by Millimeter VLBI
The advancement of neutrino observatories has sparked a surge in multi-messenger astronomy. Multiple neutrino associations among blazars are reported while neutrino production sites are located within their central (sub)parsecs.

Multi-Wavelength Intra-Day Variability and Quasi-Periodic Oscillation in Blazars
We reviewed multi-wavelength blazars variability and detection of quasi-periodic oscillations on intra-day timescales. The variability timescale from a few minutes to up to less than a days is commonly known as intra-day variability.

X-ray Spectral Evolution of High Energy Peaked Blazars
The synchrotron hump of the high energy peaked blazars generally lies in the 0.1–10 keV range and such sources show extreme flux and spectral variability in X-ray bands. Various spectral studies showed that the X-ray spectra of high energy peaked blazars

Immunohistopathology of oral mucosal chronic graft‐versus‐host disease severity and duration
Abstract Objective Chronic graft‐versus‐host disease (cGVHD) is the main cause of late non‐relapse mortality following hematopoietic cell transplantation. Oral mucosal (om‐) cGVHD is common, but diagnosis and assessment rely on clinical interpretation and patient‐reported symptoms.
